I LOVED watching Daniel Choi in this drama, and appreciated his acting skills. He's the most photogenic, handsome, charistmatic K-actor. The cast and acting was on point. Some acting was overacting, but this is K-dramaland.

Too much detail was spent on Sun Woo-Hye and the flashbacks/flashbacking and singing. The constant loud singing in your "face" is so tiresome in the Asian dramas. If they had shown the sequence of events in chronological order, instead of flashbacking constantly, the story would have flowed effortlessly instead of listlessly like the ocean tides. This could have improved the Korea TV ratings significantly.

Some of the plot was confusing, confounded by the repetitive flashbacks and flashbacking. "I see you, Lee Da Il. I don't see you, Lee Da Il." Once the characters started talking directly to Lee Da Il, when they were not really seeing him, was a conspiracy among the Director, Scriptwriter and Film Editor. The story dragged in places, especially with Sun Woo-Hye on screen. The whole story could have been told in 16 30-minute episodes, or it could have been a very good 2-hour movie.

Spoiler: Lastly, the five years' time jump at the end! Really, Director? Really, Writer? This "love" story qualifies for the 1,000 or 10,000 years' old romance drama.
